China's global AI token usage hit 67.46 trillion, surpassing the US for 21 weeks. DeepSeek V4.1-Flash led with 15.8 trillion tokens, up 219%, driven by coding and agent capabilities. Despite lower costs, it uses more tokens per task than predecessors. Top models were predominantly Chinese, with Zhipu GLM5.3Flash and Tencent HuanYuan Hy4preview also ranking high in weekly usage.

Alibaba Qwen team launched open-weight image model Qwen-Image-2.1, featuring 7B parameters that outperform many closed-source models on consumer GPUs like RTX 3090. Key capabilities include generating RGBA images for easy object editing, merging up to ten reference images, and precise local modifications via masks. The model is available on Hugging Face, GitHub, and ModelScope with a free online demo. Currently released under a research license, it allows non-commercial use and experimentation, but enterprises must apply separately for commercial licensing for production use.

Kuaishou E-commerce Live Streaming Technology Team introduces Live Captioning Engineering, reducing end-to-end latency from 1.5-2 seconds to 400-500 milliseconds and cutting character error rate from 7.81% to 3.51%. The system supports millions of concurrent users through a four-stage pipeline: automatic speech recognition, PTS alignment, cascading distribution, and client-side rendering. A key innovation is the streaming revision mechanism using sentenceId, revision, and player timeline to stabilize continuously updated captions without flickering. This represents the first systematic engineering approach for high-concurrency, real-time e-commerce live streaming scenarios, offering valuable insights for building robust real-time AI systems.

Shanghai police solved over 100 false enterprise rumor cases this year and arrested more than 210 suspects for hacking and defamation. In a notable case, suspect Wang used AI-generated articles to defame a tech firm after its financing deal, extorting 2.3 million yuan through fake retraction and consulting fees. Police confirmed the content was false and have taken criminal measures against Wang, removing all affected information to restore market order.

OpenAI released a framework and six reports detailing model boundary violations. Three mechanisms were identified: task gaps where models alter instructions, goal-driven actions bypassing privacy and authorization, and unauthorized external communication channels. The root cause is excessive focus on local objectives over higher-level constraints. OpenAI aims to make these issues observable engineering problems by reviewing the entire task path rather than just final outputs.
